Title: Improvements in or relating to blading arrangements for turbo-machines
Inventor: BAUGER LOUIS JULES
IPC: F04D29/32
Filed: 1968-12-05
Abstract: 1,235,006. Turbines; axial flow compressors; jet propulsion plant. SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Dec. 5, 1968 [Dec. 12, 1967], No. 57836/68. Headings F1C, F1J and F1T. A two-tier blade ring for a turbomachine such as a compressor ducted fan or the like comprises angularly spaced blades each formed by an inner section 2 having a tip portion 5 and a radially aligned outer section 3 having a base portion 6a mounted in a groove 6 in the tip 5. The blade sections 2, 3 are exposed to different working fluid flows, such as two air-flows or flows of air and combustion gases, and are separated by an annular member 1 having circumferentially spaced apertures engaging the tips 5 to strengthen the assembly. Insertion of each base 6a in its groove 6 is facilitated by a groove 7 in the member 1 in alignment with each aperture. As shown, the blades may be variable pitch having a spigot 4 secured in taper-roller bearings 8 in an annular member 9 fixed to the shaft r of a gas turbine engine compressor. Each spigot 4 carries Fig. 1, a gear 10 meshing with a rack 11 on an arm 12 secured to an axially slidable sleeve 13 mounted on shaft r. A hydraulic jack or other pneumatic, mechanical or electrical device can actuate the sleeve 13 to vary the blade pitch. In a modification, Fig. 6, the pitch varying mechanism comprises a toothed sector 21 secured to each spigot 4 and meshing with a gear 22 mounted on shaft r. Normally gear 22 rotates at the same speed as shaft r but can be rotated relative thereto to effect variation of the blade pitch. Fig. 5 (not shown) illustrates an arrangement in which two succesive two-tier compressor rotor stages have pitch varying mechanism as shown in Fig. 1, the respective control sleeves 13 being slidable in mutually opposite directions by a common hydraulic actuator (16) fixed to stator structure between the rotor stages. The two-tier stator blade rings (15) of the compressor may also be constructed similar to Fig. 1 with fixed or variable pitch blades.

Patent GB-2032093-A (GB)
Title: Solar radiation collectors
IPC: F24S23/00
Filed: 1978-10-14
Abstract: A solar energy collector comprises a transparent cover (1) which collimates incident rays of light and consists of a lamination of transparent plastics or glass elements (8). Sunlight incident on the cover over a range of angles is reflected internally between the sides (9, 10) of the elements which are curved so that the horizontal distance between the sides of adjacent elements remains constant whereas the length of a normal between the sides increases along the path of incident light. These apparently diverging surfaces cause each subsequent internal reflection at a particular internal surface to occur at a successively lower angle of incidence, thus tending to collimate the light's rays. The resulting collimated rays are refracted upon leaving the bottom of the collector cover towards an absorbing target (3) for use, for example, in heating and/or cooling buildings. <IMAGE>
